IMPROVEMENT IN FANNlNG-MILLS.

Specification forming part of Letters Patent No. 137,185, dated March 25, 1873.

To all whom it may concern:

Be it known that I, LYMAN H. DECKER, of Sauk Centre, in the county of Stearns and State of Minnesota, have invented certain new and useful Improvements in Fanning-Mills; andIdo hereby declare that the following is a full, clear, and exact description thereof, that will enable others skilled in the art to which it appcrtains to make and use the same, reference being had to the accompanying drawing and to the letters of reference marked thereon which form a part of this specification.

The nature of my invention consists in the construction and arrangement of a fanningmill, as will be hereinafter more fully set forth. In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which- Figure lis a longitudinal vertical section of my farming-mill, and Fig. 2 is a side view of the reversible shaking grainspout.

A Arepresent the corner posts or legs of my fanningfmill, which are grooved to receive the sides B B, and the whole mill fastened t0- gether by headed rods or bolts aV a and nuts, so that the mill can betakendown and packed in small compass for shipment, and be readily put up again. C represents the fan, which may be constructed in any of the known and usual ways. The drum D around the fan C is not made round, as has heretofore always been the case, but is made square or rectangular, it being formed of the sides and back of the mill with a dat top, the wind-holes b A being made in the sides of the mill.

ranged as shown in the drawing, eachscreen having at its upper end a board or blank, H. Under the third screen G3 is a board or blank, H', which extends forward nearly to the front end of the screen, so as to carry all the grain which passes through said screen up to the upper end of the lower gang of screens I1 and I2. These latter screens are arranged as shown, the top screen I1 extending further in rear than the lower screen I2, dividing the grain into two qualities, No. 1 and No. 2.

, Both qualities empty into one spout, J, one on each side of a partition, d, which divides the spout its entire length. Measures are to be placed under the spout to receive the two grades of grain as it passes out.

The partition d may be removed when defr sired, and the two grades will be mixed t0 gether.

The spout J is hung on a rod, 1L, and shakes on the same, and it can be readily removed and reversed so as to cause the grain to pass out on either side of the mill, as may be most convenient. A

K represents the screen-drawer under the sieves Il I2. W represents the shoe attached to the side of the mill, and that part next to the fan is made circular or to conform to the size of the circle inscribed by the fan when the same is in motion, by which means the fan is allowed to be placed forward, so that a portion of the fan operates directly under the upper screens, giving a stronger blast than it otherwise could where the fan is placed back in the ordinary manner.

Having thus fully described my invention, what Iclaim as new, and desire to secure by Letters Patent, is

1. In a fanning-mill, a square or rectangular drum, D, surrounding the fan, substantiall y as and for the purposes herein set forth.

2. The spout J hung upon a shaking-rod, h, and provided with a central longitudinal partition, d, substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this. 25th day of January, 1873.
